A new toy for climate change sceptics is announced . The 'Our Climate iPhone app'. It gets reviewed in the Guardian by John Cook of Skeptical Science fame. John's review points out an obvious flaw " The cherrypicking nature of climate scepticism leads to an interesting phenomenon – sceptic arguments frequently contradict each other. One week, we're told El Nino is the cause. Next week, it's cosmic rays. No wait, we're cooling... Hold on, it's warming again, but this time, it's because of CFCs. Could anyone compile the many sceptic arguments into a single app without a mess of contradictions?"

In a nutshell climate change denial goes no deeper than what can fit on an iPhone app.

What climate change denial really needs is creativity. A new way to say the same old bollocks. Step up to the plate Australian blogger Jo Nova . "Really, this is a great endorsement" , writes Jo . To arrive at this conclusion Jo asks "Has he found errors, lies, or critical omissions?" Well, yes actually, but Jo answers the question for us and those exact words aren't used in John's review.

The flaw in Jo's argument is apparent. She is saying that any criticism that fall's short (in her view) of this yardstick amounts to an endorsement of her creed. It's a belief she is entitled to. But it's only that , a belief, it's not a scientific view. Moreover it demonstrates the bias that Jo Nova applies in her evaluations.
